The third group, P1: 104.986094414, P2: 5.673990841, P31.725886115, P4: 170.116966453, P5: 0.142948990, P6: 0.027735512, P7: 0.151842325, P8: 0.089028594, P9: 6.412016343, P10: 1.584950290, P11: 0.067264966, P12: 0.004003946, P13: 0.001528705, P14: 0.000177050, P15: 0.060214354. The embodiment of the present invention provides a specific formula for the second model, thereby improving the accuracy of determining the current air-conditioning load based on the second model.

[0059] S102, determining a target switching temperature difference using a first model according to a current air conditioning load and a first target parameter, so as to determine an air conditioning operation mode based on the target switching temperature difference; wherein the first model is a model determined based on the relationship between the first target parameter, the current air conditioning load and the switching temperature difference.

[0060] This embodiment does not limit the specific first model. For example, the first model in this embodiment can be an intelligent model of the target switching temperature difference corresponding to the current air conditioner when the input is the rated switching temperature difference corresponding to the first target parameter and the current air conditioning load; or the first model in this embodiment can also be a formula based on the current air conditioning load and the first target parameter. This embodiment does not limit the specific time of determining the rated switching temperature difference. For example, this embodiment can obtain the rated switching temperature difference corresponding to the first target parameter when obtaining the first target parameter; or the rated switching temperature difference in this embodiment can be directly the value in the first model. This embodiment does not limit the update time of the target switching temperature difference. For example, the update time of the target switching temperature difference in this embodiment can recalculate the target switching temperature difference based on a set time period; or this embodiment can also recalculate the target switching temperature difference when entering the compressor mode. The air conditioning operation modes in this embodiment include compressor mode and fluorine pump mode. It can be understood that this embodiment can determine the target switching temperature difference using the first model according to the current air-conditioning load and the first target parameter. The specific coefficient of the current air-conditioning load in the first model is first determined based on the first target parameter to obtain the target switching temperature difference. Alternatively, this embodiment can also use the first target parameter and the current air-conditioning load as input to obtain the switching temperature difference under the first target parameter and the current air-conditioning load.

[0061] It should be further explained that, based on any of the above embodiments, before determining the target switching temperature difference by using the first model according to the current air-conditioning load and the first target parameter, the following may also be included:

[0062] S1021, obtaining the rated refrigeration capacity of the fluorine pump related to the switching temperature difference;

[0063] S1022, determining a first model according to the rated refrigeration capacity of the fluorine pump and its corresponding rated switching temperature difference, and the hysteresis temperature; wherein the hysteresis temperature is a constant term in the first model.

[0064] The first model in this embodiment can be b=c+Q1*30 / Q, wherein b is the target switching temperature difference, c is the return temperature, Q1 is the current air conditioning load, Q is the first target parameter, and 30 is the rated switching temperature difference. For example, the first target parameter is the rated cooling capacity of the fluorine pump. This embodiment gives a specific formula for the first model. After determining the rated switching temperature difference corresponding to the rated cooling capacity of the fluorine pump, the target switching temperature can be directly determined based on the current air conditioning load, so the efficiency of determining the current air conditioning load based on the first model can be improved.

[0065] It should be further explained that, based on any of the above embodiments, after obtaining the current air-conditioning load, the following steps may also be included:

[0066] S1, obtaining a third target parameter related to the maximum refrigeration capacity of the fluorine pump;

[0067] S2, determining the current maximum refrigeration capacity of the fluorine pump using a third model according to the third target parameter; wherein the third model is a model determined based on the influence relationship between the third target parameter and the refrigeration capacity of the fluorine pump;

[0068] S3, judging whether the first condition is met; wherein the first condition is that the current maximum cooling capacity of the fluorine pump is greater than or equal to the current air conditioning load;

[0069] S4, if the first condition is met, determining the mode to be the fluorine pump mode;

[0070] S5: If the first condition is not met, determine that the mode is the compressor mode.

[0071] The specific third target parameter is not limited in this embodiment. For example, the third target parameter in this embodiment can be the indoor and outdoor temperature difference; or the third target parameter in this embodiment can also be the condensing pressure, return air temperature, etc. The third model in this embodiment can be Q2=Q*(ac) / 30; wherein a is the current indoor and outdoor temperature difference (indoor temperature-outdoor temperature), c is the hysteresis which can be set (for example, it can be 2, 3, etc.), Q is the nominal fluorine pump rated cooling capacity of the unit, and Q2 is the current maximum cooling capacity of the fluorine pump. This embodiment calculates Q1 (current air conditioning load) and Q2 (current maximum cooling capacity of the fluorine pump) to determine whether the condition Q2≥Q1 is met. If it is met, it proves that the current fluorine pump refrigeration capacity meets the current load requirements, and the fluorine pump operation is switched on. If not, the compressor mode continues to operate. This embodiment provides a specific switching method for the air conditioning operation mode, which improves the accuracy of the air conditioning operation mode switching.

[0072] It should be further explained that, based on any of the above embodiments, if the first condition is met, after determining that the mode is the fluorine pump mode, it may also include: judging whether the second condition is met; wherein the second condition is that the target switching temperature difference is less than the indoor and outdoor temperature difference; if the second condition is met, it is determined to continue to run the fluorine pump mode; if the second condition is not met, it is determined to exit the fluorine pump mode and enter the compressor mode. In this embodiment, if the fluorine pump mode is entered, according to the target switching temperature difference b, the first condition is judged: b<a (indoor and outdoor temperature). If it is met, it proves that the current fluorine pump refrigeration capacity meets the load requirements before switching, and the fluorine pump mode can continue to run; if it is not met, it proves that the current fluorine pump refrigeration capacity does not meet the load requirements before switching, and it is necessary to exit the fluorine pump mode and re-enter the compressor mode.

[0073] It should be further explained that, based on any of the above embodiments, if the second condition is met, it is determined to continue to run the fluorine pump mode, and it can also include: judging whether the third condition is met; wherein the third condition is that the cooling capacity is less than or equal to the set cooling capacity threshold; if the third condition is met, it is determined to continue to run the fluorine pump mode; if the third condition is not met, it is determined to exit the fluorine pump mode, enter the compressor mode, and re-execute the step of determining the target switching temperature difference based on the current air-conditioning load. In this embodiment, the cooling demand is ≤100 (the set cooling capacity threshold can be 100, or 105, etc.). When the fluorine pump is running, if the second condition is met, but the cooling demand continues to increase and does not meet the third condition, it means that the load of the computer room has changed and the fluorine pump operation conditions are no longer met. It is necessary to exit the fluorine pump mode and enter the compressor mode to recalculate the current air-conditioning load. This embodiment provides the opportunity to recalculate the current air-conditioning load, which improves the accuracy of updating the target switching temperature based on the current air-conditioning load.

[0074] The method for determining the air-conditioning operation mode provided by the embodiment of the present invention may include: S101, obtaining the current air-conditioning load and the first target parameter related to the switching temperature difference; S102, determining the target switching temperature difference using the first model according to the current air-conditioning load and the first target parameter, so as to determine the air-conditioning operation mode based on the target switching temperature difference; wherein the first model is a model determined based on the relationship between the first target parameter, the current air-conditioning load and the switching temperature difference. Compared with the current method of directly setting the switching temperature difference as a fixed value, the present application can determine the target switching temperature difference using the first model based on the current air-conditioning load and the first target parameter. Since the target switching temperature difference will change according to the change of the current air-conditioning load, it is possible to dynamically determine the switching temperature difference based on the air-conditioning load, thereby improving the accuracy of determining the switching temperature difference, thereby improving the accuracy of the subsequent determination of the air-conditioning operation mode based on the switching temperature difference.

[0075] In order to make the present invention easier to understand, please refer to Figure 2 , Figure 2A flow chart of a method for determining a switching temperature difference provided by an embodiment of the present invention may specifically include:

[0076] S201. Detect the condensing temperature z using a condensing pressure sensor, detect the evaporating temperature y and the compressor frequency x using an evaporating pressure sensor, and calculate the current air conditioning load Q1 according to a load model Q1=f(x,y,z).

[0077] Q1=f(x,y,z) in this embodiment is: Q1=P1+P2*y+P3*z+P4*x+P5*y*y+P6*z*z+P7*x*x+P8*y*z+P9*y*x+P10*z*x+P11*y*y*x+P12*y*x*x+P13*z*z*x+P14*z*x*x+P15*y*z*x, where P1-P15 are fitting coefficients of different compressors. Q1=f(x,y,z) in this embodiment corresponds to the second model above.

[0078] S202. Determine the target switching temperature difference according to the current air conditioning load using the switching temperature difference model b=f(Q1); wherein the switching temperature difference model is a model determined based on the relationship between the current air conditioning load and the switching temperature difference.

[0079] In this embodiment, b=f(Q1) (corresponding to the first model above) is b=c+Q1*30 / Q, where Q is the rated refrigeration capacity of the nominal fluorine pump of the unit, and Q corresponds to the first target parameter above.

[0080] A method for determining a switching temperature difference provided by an embodiment of the present invention, compared with the current method of directly setting the switching temperature difference to a fixed value, the present application can determine the target switching temperature difference based on the current air-conditioning load using a first model. Since the target switching temperature difference will be dynamically adjusted according to the air-conditioning load, the switching temperature difference can be dynamically determined based on the air-conditioning load, thereby improving the accuracy of the switching temperature difference determination.
